Memory leak detection

A computer-implemented method, comprising:

• monitoring one or more containing classes in a production environment;
• identifying which of the one or more containing classes hold at least one static or non-static field of collection or array type;
• accessing the one or more containing classes that hold the at least one static or non-static fields of collection or array type;
• tracking a size for each field of each containing class by periodically sampling the size of each field over an interval, the one or more fields of each containing class enabling instances of each containing class to maintain at least one of state and behavior;
• processing the size data for each field of each containing class;
• and
• detecting suspected memory leaks of each containing class by identifying which of the one or more fields of each containing class exhibits suspect behavior in the size over the interval.

A computer program product, the computer program product being tangibly embodied on a non-transitory computer-readable medium and comprising instructions that, when executed by at least one processor, are configured to:

• monitor one or more containing classes in a production environment;
• identify which of the one or more containing classes hold at least one static or non-static field of collection or array type;
• access the one or more containing classes that hold the at least one static or non-static fields of collection or array type;
• track a size for each field of each containing class by periodically sampling the size of each field over an interval, the one or more fields of each containing class enabling instances of each containing class to maintain at least one of state and behavior;
• process the size data for each field of each containing class;
• and
• detect suspected memory leaks of each containing class by identifying which of the one or more fields of each containing class exhibits suspect behavior in the size over the interval.
